INVENTOR f/mef Sas BY ATTORNEY Patented July s, 1932 UNITED STATES PATENT ol-FlcE ELHEB SAS, Oilj NEW YORK, N. Y., ASSIGNOB TO THE PEBSER CORPORATION, 0F NEW YORK, N. Y., A CORPORATION OF NEW YORK MEANS TO PROTECTOORNERS OF FRANGIBLE MATERIAL Application fled March 29, 1930. Serial No. 439,893.

My invention relates to devices designed to protect the corners of glass plates, by providing a protective covering Yof metal which, when in use, will provide for a space interme- 3] diate the covering and the corner of the glass plate, and thus more eiectually protect the glass than would be the case if the metal simply covered the edge of the plate but was in contact therewith; and more specifically re- 10. lates to devices of the character which protect the edges of the glass plates and provide for a space between the plates and the metal binding.

My invention has for its object, to provide a metal covering for the corners, which will not only protect the same from accidental injury but which can be quickly and easily attached or detached, and to accomplish this result in an inexpensive manner.

illustrated in the accompanying drawing, which is to be considered as a part of this specification, in whicht Fig 1 is a front elevation of my new device;

Fig. 2 is a side elevation of the same;

Fig. 3 is a fragmentary cross-section of a corner; and

Fig. 4 is a detail view of a corner.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawing, the glass plates 1 and 2 are provided with metal binding- 3,

and consists ofa channel, the base 4 of which is held in'spaced relation to the edge 5 of the plates 1 and 2.

Mv protective covering comprises a corner 6, which is stamped or blanked out of sheet metal. The metal is then formed into a corner, each angle of which is bent. as at 7,forming an oiset portion 8, which is adapted to be inserted intermediate the base 4 of the metal binding 3 and the edge of the plates 1 and 2. This offset 8 serves to hold the remainder of the angle spaced from the corners of the plates 1 and 2, thus eifectually safeguarding them even if they should be struck quite a blow. The shoulders 9 formed by the A concrete embodiment of my invention is4 which extends longitudinally of their edges,

bend 7 serve'to hold the corners from movement.

As each angle is of identical conguration,l

it follows that when the offset portions 8 on each angle are inserted in place, the corners cannot be accidentally displaced', although they can be easily removed or placed in position, the springiness of the metal serving to hold them, once they are placed inside the metallic binding.

It will be apparent from the foregoing description that these corners may be blanked out of sheet metal, as clearlyl seen in Fig. 4, by a punch press, and then formed into their linal shape. This kind of work being very cheap, I am enabled to produce a very inexpensive covering for the corners, and thus reach the result sought to be obtained.

Although I have described the corners as.

being formed of metal, andthe plates as being glass plates, I do not wish to be understood as limiting myself specifically to the kinds of material named. as my invention is not confined to any particular material.

Having described my invention, what I regard as new, and desire to obtain by Letters Patent of the United States, is:

1. The combination, with a glass plate provided with a binding which is spaced from the edge of the plate, of detachable corners formed of springy material, each angle of which has an offset end portion adapted to be inserted intermediate the plate andthe binding. the corner being spaced from the corner of said plate.

2. In a device of the character described, a

detachable corner comprising angles formed of relatively stiif resilient material adjacent the corner. having end portions. and a shoulder formed at the junction of the angle and the end portion, said end portions being oifset.

' 3. The combination, with a plate, of a detachable corner formed from relatively stiif sheet metal, each angle thereof having an olfset end portion, whereby the corner is spaced from the corner of the plate, and means to detachablyhold said corners in position.

4. The combination, with a plate provided with binding which is spaced from the ed'ge of the plate, of detachable crners formed of springy material, each angle of which has an offset end ortion adapted to be inserted 5 intermediate t e plate and the bindin the corner being spaced from the corner o said plate.
